xbox one which turns off a few seconds after startup

Thanks, just to be specific - it turns ON but does not startup and xbox light goes off after a few seconds. Xbox does not start.

Hi HallowedRobin,

Sorry you're having issues with your console. When you say multiple power cords are you referring to power strips? What color is the power supply when it turns off? It could very well be an issue with the Xbox Power Supply which does not cost as much money
as the console to service. See this link for troubleshooting on your power supply. Use the
Xbox Service Center to process repair requests for your power supply and your console.

Hey JaradWebb, how are you today? Hope you're well.

JaradWebb, I'm so sorry for the trouble you're having.

It seems like your console might be having an issue within its hardware. Could be also the power brick, would be a good idea to test another one. But, I recommend taking your console to a repair store in your region, since Microsoft doesn't offer repair services for the Original One anymore due to that model is not manufactured anymore. :/

Sorry, but talking about self repair is not allowed on these forums. You will have to post somewhere else for help with the issues you are having.

Hello Chris W! I'm Kris and I'd be happy to help you with your question.

Sorry to hear you are having issues with your Xbox One. Sounds like you have already done a lot to try and fix it. Changing the power supply was a good move. Unfortunately, it sounds like there is a hardware issue related to power within the console which would requires to be fixed.
